Communication problem or something more?

Post by oh6hps » Sat 14 Jul 2018 2:54 pm

Problem:

Cumulus MX freezes after running about 1h or so. My set up worked many months without any major issues until last Thursday. Nothing has changed with my setup prior problems. The temperature outside is quite high now (31°C) and it might affect to my Raspberry which is located in the attic.

Setup:

Davis VP2 + IPLogger (latest fw´s) -->Meteobridge --> Raspberry Pi 2 (mono 4.0.5) Cumulus MX v3.0.0 (3043).

Any suggestions where to start finding the problem. Maybe the attached debug log tells something to you gurus. ;)

Thanks in advance!

Looks like some kind of communication issue, data stops arriving from the console. That's all you can tell from the Cumulus log.

Thanks for the prompt reply, Steve. Yes, I think so too. A root cause may be the heat as we talk about Raspberry. My first guess was the memory card, but not anymore. We`ll see if upcoming night helps with the heat. Can you believe, heat issues in Finnish summer... :D

I restarted the console before midnight and everything seems to be ok since then. Fingers crossed...

Something similar I created when I was having problems with a randomly disconnecting USB hub can be found in this post Using the RPI it will search certain generated files for keywords that will trigger an automatic reboot should the need arise.
